Factors to Consider when Buying 8-Inch Subwoofer

Power

Well, power is usually the first thing a buyer starts to look for. It makes total sense that you should look for this value in a subwoofer’s specs. However, there are two kinds of powers to keep an eye on.

RMS Power

RMS power refers to the amount of power a subwoofer can handle. This is the value that really matters in a subwoofer. If you need a powerful subwoofer, look for the RMS power in the specs.

Also, make sure that this value matches the amplifiers. The amp should be able to pump out 75 to 150 percent of the subwoofer’s rating. The RMS power is what gives you the boom.

Peak Power

This is another aspect of power in a subwoofer. But this quantity is not much important as it only affects the performance to a limited extent. The peak power represents the maximum voltage that can be handled in short bursts for a limited amount of time.

Sensitivity

This is another value that determines the sound quality and performance of a subwoofer. The more sensitive a subwoofer is, the more efficiently it will convert power into output volume. Power without enough sensitivity would not produce the desired results in a subwoofer.

Number of voice coils

Going for a dual voice coil speaker has a few advantages over a standard speaker. These offer more control of impedance, offer more wiring options to take advantage of the amplifier. However, there is no direct advantage of a dual voice coil over a single voice coil.

Frequently Asked Questions

Which is better between 2 ohm or 4-ohm subs?
